Answer:

7 7/4 t - 1

Step-by-step explanation:

The perimeter of the quadrilateral is the sum of all the sides combined together

Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),

Taking the sum;

Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)

Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2

Collect like terms;

Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2

Perimeter = (9t-2t)/4 + 7t -1

Perimeter = 7/4 t + 7t - 1

Perimeter = 7 7/4 t - 1

Construct a 95​% confidence interval to estimate the population mean using the data below. x overbarequals37 sigmaequals10 nequa
kap26 [50]

Answer:

With 95% confidence when n equals 44, the population mean is between a lower limit of 33.96 and an upper limit of 40.04

Step-by-step explanation:

Confidence Interval = mean + or - Error margin (E)

mean = 37

sd = 10

n = 44

degree of freedom = n - 1 = 44 - 1 = 43

t-value corresponding to 43 degrees of freedom and 95% confidence level is 2.0165

E = t × sd/√n = 2.0165×10/√44 = 3.04

Lower limit = mean - E = 37 - 3.04 = 33.96

Upper limit = mean + E = 37 + 3.04 = 40.04

95% confidence interval is between 33.96 and 40.04

PLEASE HELP ME :) I DID THIS PROBLEM 7 TIMES AND ITS STILL WRONG PLEASE
fiasKO [112]

Answer: $95450

Step-by-step explanation:

We obviously want to look in the 3rd column.

Income that can be taxed is within interval for 33%, so (0.33)(315000) = $103950.

Subtract the tax credit, and we get $103950 - $8500 = $95450.
